Hybrid vehicles pose dangers to pedestrians

Environmental enthusiasts and those looking to save on gas have long touted the benefits of owning a hybrid vehicle. The motor vehicle's sleek design and quietness have been optimal for those living in congested cities. For most, it's difficult to find fault in eco-friendly rides.

However, the visually impaired may not share such rosey sentiments towards hybrids. These pedestrians are just one segment of the population that can be negatively affected by the quiet vehicles.

The Boston Globe reports research is underway to determine the safety risks associated with hybrid vehicles. At speeds less than 20 mph, hybrids can be essentially silent. Friction between car tires and the road create noise at faster speeds regardless of the type of vehicle.

"This is an example of too much of a good thing," National Federation of the Blind executive director for strategic initiatives John Pare said according to the paper. "Cars got quieter, that was good. Suddenly they got to be so quiet that it added an element of danger."

It's important for drivers to always use safe driving practices and be mindful of pedestrians. A person may not see, or hear, a vehicle and may walk into traffic.
